J. W. GARDNER cANI'sTER `coNTINER Filed Aug. e, 1938 Patented Nov.`21,1939 H 2,180,806 CANISTER CONTAINER John Wilfred Gardnerjliiverpool,England Application AugustA 6, less, serial No. 223,534 In Great BritainJanuary 12, 1938 Claims-y (Cl. 221 19) f l .This invention relates to animproved construction of canister for powders or granular material,whether of cylindrical drum or other shape, and whether of compositecardboard and tin-plate 5 construction or made entirely of sheet metal.

AAccording to the present invention, a canister container is providedwith` a lid having a recess, an outlet aperture in the lid recess, apouring spout, a flange on the base of the pouring spout, saidk spoutflange being movably mounted in the lid recess, a disc secured on thelid, an aperture in said disc through which the spout projects, the rimof said disc aperture projecting over the spout ange `to retain thespout on the lid, and an outlet aperture in the pouring spout baseregistering Witnthe outlet aperture in the lid recess when the spout ismoved to an operative pouring position, and being out voffregister withthe outlet aperture in the lid recess when the pouring spout 'ismoved to'an'inoperative position.

Means are preferably provided for preventing accidental movement of thespout from an inoperative position as may occur during transport. Thespout may be retained in position on the lid by means of a discextending over the whole of the lid, the disc being secured in positionas by means of tongues punched up from the lid and riveted in the disc.

In the accompanying drawing: l Fig. 1 is an elevation partly in sectionshowing ,the invention applied to a cylindrical drum canister,

Fig. 2 being a plan and Fig. 3 a vertical section through thepouringhaving means for preventing accidental uncover-l {ing of thepouring aperture during transport.

In the construction illustrated in Figs. 1 to 6 \the sheet metal lid Iof the canister 2 is formed with a circular depression or recess 3 inthe base of which is an eccentrically disposed aperture 4;

a pouring spout 5, which may be moulded from synthetic resin, isinserted into the recess, a circular ange 6 at the base of the spoutfitting the recess.

A cardboard disc insert 1 of the size of the canister lid is thenpositioned over the spout toenclose theflangefin the recess, a circularaperture 8 in the disc fitting closely round the smaller neck vof thespout and providing .an annular lip extending over the flange. The discmay be-held in position on the lid to retain the 5 spout either by itsperiphery being snapped past an annular ridge 9 on the lid or beotherwise secured, as by means of tongues I0 punched up from the vlidand riveted in thev disc.y In the spout is formed a vertical hole I I,also eccentrically dis- 10 posed, leading from the base to a recess I2`-in the top of the spout, one side ofthe spout termi--r nating in a lipI3. The recess 3 in the canister lid is preferably disposed near theside so that whenthe spout is turned to the position shown 15 in fulllines, Fig. 2, with its lip projecting slightly over the rim of thecanister, the hole II in the spout registers with the pouring aperture 4in the head I and the contents may then be freely poured out. When thelip of the spoutis turned 20 towards the centre of the canister-to theposition shown in dotted lines-the pouring aperture isshut off. Byforming the recess I2 in the top ner and engaging over the shoulder 6 onthe 30 spout. In order to prevent the spouts of canisters working roundduring transport from a closed position, indicated in full lines Fig. 8,to an open position, indicated in dotted lines, which move- 35 mentmight accidentally occur owingto vibration set up by the transportvehicle or other cause, theundersurface of the spout may be formed withtwo separated concentrically'curved grooves I6,

I1, a nib I8 being pressed up from the metal of 40 the lid I in such aposition that it will register with and engage one or other of` thegrooves I6, I'I when the spout is positioned in the recess 3. When inthe closed position shown in Fig. 8 with the Anib I8 engaging the grooveI6, the 45 spout Will be prevented from rotating outwardly to such anextent as would uncover the lid aperture 4- because the ends of thegroove I6 will be engaged by the nib I8 thus limiting the angulardisplacement which could be caused accidentally, 50 so preventinguncovering ofthe aperture 4 and preventing loss of material duringtransport. When it is required to turn the spout to an operativeposition uncovering the aperture 4, this may be effected manually bygiving the spout a 55 the base having an eccentric aperture adapted toregister with that in the recess in the canister lid when the spout isturned to the operative position.

The term disc in the description and claims is intended Vto include notonly parts of circular shape but also other plate-like members ofsquare, rectangular or other shape.

I claim:

1. In a canister container, a lid having a recess, an outlet aperture inthe lid recess, a pouring spout, a flange on the base of the pouringspout,

said spout flange having its upper face flush with the yupper surface ofthe'lid and being movably mounted in the lid recess, a flat disc securedon the lid, an aperture in said disc through which the spout projects,the rim of said disc aperture projecting over the spout'ange to retainthe spout on the lid, and an outlet aperture in the pouring spout baseregistering with the outlet aperture in the lid recess when the spout ismoved to an operative pouring position, and being out of register withthe outlet aperture in the lid recess when the pouring spout is moved toan inoperative position.

2. In a canister container, a lid having a circular recess, aneccentrically disposed outlet the upper surface of the lid and beingrotatably mounted in the lid recess, a flat disc secured on the lid, anaperture in said disc through which the spout projects, the rim of saiddisc aperture projecting over the spout flange to retain the spout onthe lid, and an eccentrically disposed outlet aperture in the pouringspout base, said pouring spout aperture registering with the outletaperture in the lid recess when the spout is rotated to an operativepouring position, and being rout of register with the outlet aperture inthe lid recess when the pouring spout is rotated to an inoperativeposition.

3. A canister container according to claim 2, in which the apertureddisc extends over the whole top surface of the canister lid.

4. A canister container according to claim 2, in which the apertureddisc is in the form of a narrow ring.

5. In a canister container, a lid having a circular recess near oneside, an eccentrically disposed outlet aperture in the'lid recess, apouring spout, Va circular ange on the base of the pouring spout, saidspout ange being rotatably mounted in the lid recess, a disc secured onthe lid, an aperture in said disc through which the spout projects, therim of said disc aperture projecting over the spout flange to retain thespout on the lid, an eccentrically disposed outlet aperture in thepouring spout base, said pouring spout aperture 'registering with theoutlet aperture in the lid recess when the spout is rotated to anoperative pouring position, and being out of register with the outletaperture in the lid recess when the pouring spout is rotated to aninoperative position, two separated and concentrically curvedgrooves onthe undersurface of the spout flange, and a nib in the recess forregistering with and engaging one or other of said grooves.
